No Navigation - Here Drive+

After getting Here Drive+ on my 950XL it was smiles all round. BUT following the recent firmware update when I go to navigate I get 'No Navigation Your route runs through a country or area where navigation isn't available yet'. Now that clearly is a lie. There are 2 950XL's in our house and they both say the same. Have uninstalled Here Drive+ deleted maps and reinstalled but still no navigation. Heres' replacement MS's Maps still navigates.

I like Here maps as it is clearer to read when driving. The onboard MS maps is dangerous as the text is so small. MS obviously are not looking at the usability but just the functionality. Here maps has a much more readable and information UI
